TNGA 160408 DX140 Turning Insert (PCD) by Tungaloy — AddMultiTurn compatible

The TNGA160408 DX140 is a triangular indexable insert engineered for multidirectional turning, optimised for aluminium, non-ferrous metals and abrasive non-metals in single-tool multi-directional operations.

• PCD DX140 for aluminium and non-ferrous
• Triangular 60° geometry, 0.8 mm corner radius
• Compatible with AddMultiTurn multidirectional system
• Cylindrical-hole design for secure clamping

High-speed turning performance for demanding non-ferrous work

The polykristalline diamant cutting layer PCD in grade DX140 enables significantly extended tool life and makes the insert particularly suited to aluminium and other non-ferrous or abrasive non-metal applications. By using a diamond cutting surface rather than standard carbide at the cutting edge, the insert sustains high speeds and long abrasion resistance, which translates into fewer tool changes and higher net productivity for repetitive turning tasks. This performance advantage helps to lower per-part machining cost while maintaining process stability.

Precise geometry for consistent surface quality and stability

The triangular layout with a 60° cutting angle and 0.8 mm corner radius provides a balance between edge strength and fine finish capability. The combination of a 4.76 mm plate thickness and the cylindrical hole supports reliable clamping and reduces micro-movement under load, delivering repeatable part quality in longitudinal, facing and profiling operations. The insert’s geometry reduces vibration risk and helps achieve stable surface roughness without needing complex toolpaths.

Seamless integration into multidirectional tool systems

Designed for the AddMultiTurn model series, this indexable insert fits systems that permit multiple cutting directions with a single tool family, simplifying tooling logistics and cut planning. The AddMultiTurn concept—comprising holder, indexable plates and a secure clamping mechanism—allows efficient changing of cutting directions and reduces setup time. For straightforward matching of holders and clamping torque, technical advice from Metav Werkzeuge is available to ensure the chosen setup exploits the insert’s multidirectional capabilities and the AddMultiTurn benefits.
